Salesforce West vs Gas Company Tower

Comparing the Salesforce West and the Gas Company Tower is compelling because they were both designed by Skidmore, Owings & Merrill, yet they stand in different cities (San Francisco, CA and Los Angeles, CA), and were completed more than 6 years apart.

What this will allow us to see, is how the same firm's approach adapted to different places at roughly the same time (6 years isn't that much time when it comes to urban context and architecture).

The Gas Company Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 748ft (228m) with 52 floors above ground, while the Salesforce West reaches 600ft (183m) with 43 floors above ground.

Of course, each project may have faced different briefs or regulatory constraints, which we don't really know about and could also explain the outcome.

Both the Salesforce West and the Gas Company Tower were designed in line with the aesthetic conventions of the Postmodernism style.

The Gas Company Tower was designed at a moment when the Postmodernism style was already in decline, making it more of a lingering expression of the movement. In contrast, the Salesforce West was built when the style still carried greater cultural weight.

Both the Salesforce West and the Gas Company Tower were designed to serve as commercial towers, and that has remained their main use since their completion, serving similar roles in the urban fabric.

The Salesforce West also provides 220 parking spaces.

Both the Salesforce West and the Gas Company Tower rely on a Frame structural system.

A frame structure uses a grid of columns and beams to carry the building's loads. This frees the walls from structural duties, allowing for flexible floor plans and larger windows.

They also employ the same type of facade, a Curtain Wall facade.

A curtain wall is a non-load-bearing facade hung from the structural frame. It is anchored to floor slabs and transfers only its own weight and wind loads, allowing for sleek, glassy exteriors.
